Description: 1. Field of the Invention The present invention relates generally to digital modality modeling, such as tomosynthesis, and in particular to classifying bone types prior to dental and orthopedic procedures. 2. Description of the Related Art The field of dental diagnostics is generally concerned with locating pathologies in the dental structure, i.e. the teeth and the surrounding tissue and bone. Some of the more common pathologies are: 1) caries associated with decay; 2)fractures; 3) apical abscesses; and 4) morphologies of pulpal chambers and canals. The system and method of the present invention are primarily, but not exclusively, concerned with detecting these pathologies and with orthopedics. Early detection of dental pathologies is very important in minimizing damage. Conventional diagnosis procedures are generally performed using dental X-rays (both fixed beam and scanning beam), explorers, and other conventional equipment. Incipient caries, particularly those located within the enamel surface, often go undetected with conventional equipment. When such caries are finally found, considerable damage to tooth structure may have already occurred. Subsurface,incipient caries are located entirely within the enamel layer of the teeth. They are particularly difficult to locate using conventional diagnostic equipment and procedures. By the time such incipient caries are located, the extent of the damage isoften 17% to 23% greater than it would appear to be on a conventional X-ray negative. Dental fractures can result from bruxism (teeth grinding), trauma, etc. The dental structure that has been weakened by various causes, such as decalcification, is particularly susceptible to fractures. Fractures can assume variousconfigurations, including "craze", vertical, oblique and horizontal line patterns. Fracture patterns and configurations can be particularly difficult to locate using conventional X-ray equipment and procedures. For example, fractures which aregen
